JOHN PENN OURRY, OF NEW YORK, N. Y.

IMPROVED CONSTRUCTION OF VESSELS.

Specification forming part of Letters Patent No. 48,795, (lated July 18,1865.

To all whom it may concern:

Be it known that I, JOHN PENN GURRY, of the city of New York, State ofNew York, have invented a new and Improved Mode ot' Constructing Shipsand other Vessels, adapted either to warlike purposes or our commercialmarine; and I do hereby declare the following is a full, clear, andexact description of the construction and operation of the same,reference being had to the accompanying drawings, explanatory of theplan, and to the letters inscribed thereon, illustrating the variousparts, making a portion ot this specification, in which- Figure lrepresents a side view of a vessel partially planked and partially inskeleton. Fig. 2 represents a top plan. Fig. 3 represents a side view,partially covered and partially not. Fig. 4 represents a transversesection through a vessel constructed after my plan. Figs. 5, 6, 7, 8, 9,and l0 represent detached portions, and on an enlarged scale, of some ofthe details ot1 the vessel.-

Similar letters and other marks of reference, where they occur in theseparate gures, denote like parts in all cases.

I am aware that the frames of vessels have been made of tubular iron.This I do not lay claim to.

My invention consists in the peculiar manner in which I unite andcombine the tubular frame with the wooden frame, planking, or exteriorcovering of the vessel, so that a combined tubular iron and wooden frameshall be made without puncturing the iron by the bolts that secure theplanking or timber to each other, and by fitting and clamping themtogether to the iron frame, the effect of such combined framing being toallow the metal to expand and contract without straining the bolts orwood-work, while each frame takes its due proportion of the strain uponthe whole. To enable others skilled in the art to make and use myinvention, I will proceed to describe the same in connection with thedrawings.

The material parts of the frame are designated as follows: A is asection of the plankshear; B, the stem; C, the stern-post; I), a

false stern-post; E, a section of iron plating; F, dead-wood and aprons;G, keelson; H, section of inside planking or ceiling; I, forward apron;J, thick strake or water-Way; K, section of' main deck; L, main deck andsupplemen tal beams; M, forward breast-hook; N, main rail; O, timberfillings or chocks; P, the keel; R, wood timbers or riders for plankingwith wood; T, longitudinal or fore and aft iron pipes, crossing atintervals the vertical pipes or tubes.

Where the fore and aft tubes T meet or lie against the vertical tubesthey are clamped together by straps, as shown in Figs. l, 3, 4, or byclamps, as shown at 5 9 in Figs. 6 and 8, and in all cases so that themetal tubes shall not be perforated or the fastenings pass through them,the ohjectof this loose or play fastening or clamping being to allowfree eX- pansion and contraction ot' the metal without straining thetubes and breaking or loosening the fastenings. The form ot' thesefastenings may be varied, but I have shown but three, which will fullyexplain the objects in view.

The timber fillings or chocks O are strapped to the tubular iron frame,as shown in Fig. 3, and also to the wood timbers R, and the plankingIand ceiling bolted to said timbers. The bolts passing through thetimbers are so placed as that they shall not penetrate the metal portionof the frame, but closely embrace it between the timbers, so that itshall be a combined frame to resist strain, but leave the -xnetal freeto expand and contract.

The spaces between the tubes may be lilled with wood, so `as to leave,in connection with the timbers,flush sides to plank or ceil to, and theframes may be double, with an intervening space, as shown in Fig. 4.

The stem-piece B, with its aprons l2 and 13, Fig. 5, is fitted to thetubular frame, as shown, and held in place, as also holding the tubes,by compression, the bolts passing through the timbers, but not throughthe tubes. The keel l0 and keelson 14 are here l represented as unitedto the stern-post. The same construction may be applied to the stern andstern-post and to the deck. Iron plating may also be used in connectionwith this coml expand or contract by atmospheric changes bined metallicand wooden frame. without injury to itself or to the fastenings ofHaving thus fully described andrepresented the Wooden frame, as hereindescribed and my invention, What I claim therein as new, and'-represented.

desire to secure by Letters Patent is- A combined tubular iron and voodframe JOHN PENN CURRY' for Vessels, so united as to conjointly receive,In presence ofresist, or transmit the strain throughout the J. C.BABGOCK,

Whole, while the tubular iron fra-me is free to JOHN M. HARRINGTON.
